Abstract:

Parameters of reducing the roasting of high-magnesia oxide nickel ore containing, wt \%, 1.2 Ni, 0.026 Co, 17.0 Fe(2)O(3), 4.0 Al(2)O(3), 20.2 MgO, and 46.0 SiO(2) are evaluated. The degrees of reduction and metallization upon heating the ore with the reducing agent in the range t = 800-1250A degrees C and the sizes of metallic inclusions forming in the course of the process are determined. To separate the phases, the magnetic separation of reducing products at H = 40 and 80 kA/m is used. The best characteristics are attained upon roasting the ore with a reducing agent and a sulfidizing agent at t = 1300A degrees C. In this case, the magnetic fraction contains 7.1\% Ni, while the nonmagnetic one contains 0.18\% Ni.
